1.Ternium Mexico

Ternium is a leading company in Latin America that manufactures and processes a broad range of steel products using the most advanced technology. The company provides customers that operate in such diverse and essential steel consuming industries, such as construction, automotive and energy, as well as manufacturers of heavy and agricultural machinery, household appliances and packaging, among others.

Ternium and its subsidiaries have 17 productive centers in Argentina, Brazil, Colombia, Guate-mala, Mexico, and the United States. It is also part of the controlling group of Usiminas, a leading steelmaker of the Brazilian market.

Ternium supplies with high quality steel all the main regional markets and it also promotes the development of its customers from the metallur-gical industry. The company’s distinctive posi-tion is a result of its highly integrated produc-tion procedure. Its facilities feature the whole manufacturing process of steelmaking, from the mining of iron ore to the production of high value-added products. With a yearly achievable production capacity of 12.3 million tons, Terni-um’s shares are listed and traded on the New York Stock Exchange.

The EPD owner has the sole ownership, liability, and responsibility for the EPD. EPDs within the same product category but from different programmes may not be comparable. EPDs of construction products may not be comparable if they do not comply with EN 15804.

Environmental potential impacts were calculated according to EN 15804:2012 and PCR 2012:01

Construction products and construction services Version 2.3 (2018-11-15). This EPD is in

accordance with ISO 14025:2006.

Environmental potential impacts were calculated through Life Cycle Assessment (LCA)

methodology according to ISO 14040:2006 and ISO 14044:2006. An external third-party

veri�cation process of the EPD was conducted according to General Programme Instructions for

the International EPD® System Version 3.0. Veri�cation includes a documental review and a

validation of both the underlying LCA study and documents describing additional environmental

information that justify data provided in the EPD.

Table 5. Description of information modules included in this EPD.

Ternium Mexico manufactures hot rolled steel in three hot rolling mills, two of which (MC1 and

MC2) are in the Guerrero plant, located in the municipality of San Nicolás de los Garza, and one

mill (MC3) in the Churubusco plant, located in the municipality of Monterrey, both in the state of

Nuevo León. MC1 and MC3 mills use slab purchased to an independent supplier and the MC2 mill

has an integrated process that starts from the direct reduction of the iron pellet, through the

production of steel in the electric arc furnace, the continuous casting and the hot rolling. The

manufacturing process is depicted in Figure 1.


Figure. 1. Flow diagram of hot rolled steel manufacturing process

• Scrap purchased in the Metropolitan area of Monterrey is transported through a truck with a capacity greater than 30 t and it is acquired within the same municipality (34 km).

• All scrap acquired outside the Metropolitan area of Monterrey is purchased from Saltillo, at 80 km and transported by a truck with a capacity greater than 30 t.

• When the generation of contaminated industrial waste was reported, tow and rags were added to supplement the material balance, under the assumption that 50% by weight are tow and 50% are rags from reused garments (recycling).

• Tow and rags leave the system in the form of contaminated industrial waste or impregnated textiles and that they have the capacity to absorb 55% of their weight.

• Rags and tow used for cleaning, as well as the grease for maintenance are sourced in the same municipality.

• Natural gas consumed by Ternium Mexico comes from the Burgos gas processing complex of PEMEX and the transport distance is as follows:

Table 6. Coproduct generated in hot rolled steel manufacturing

A minimum of 95% of the total �ows (matter and energy) in modules A1 and A3 modules were

included. Company infrastructure, employee’s transportation and administrative were kept out of

the scope of this study.

5.5. Cut-off criteria

Allocation of inputs and outputs between product and byproducts was based on a mass relation,

considering the quantity produced per year of each product and byproduct at the level of unit

process.

Table 6 shows the byproducts generated during hot rolled steel manufacturing.

The polluter pays principle was applied for the allocation procedure during recycling. In this way,

in each case when there was an input of secondary material to the hot rolled steel product system,

recycling process and transportation to the site were included in life cycle inventory (for example,

steel scrap). In those cases, in which output of material to recycling were presented, material

transportation to recycling plant was included. This principle was applied to plastic and metal

containers recycled by a third party as well as waste used as energy source by third parties.

For generic data Mexicaniuh and Ecoinvent 3.3 (Allocation - Recycled Content version) databases

were used.

Parameters describing resource use were evaluated with the Cumulated Energy Demand method

version 1.09 (Frischknecht et al. 2007) except for the indicator of use of net fresh water that was

obtained from life cycle inventory (direct consumption) and with Recipe 2016 Midpoint (H)

version 1.00 (indirect consumption) (Huijbregts et al. 2017). The detailed description of the use of

resources is provided in Table 10.

* Note: AWARE method sets the maximal characterization factor (i.e. 100) for the geographical location of Ternium Works involved in Ternium hot rolled steel manufacturing. However, AWARE factor is linked to Ecosystem Water Requirement (EWR) which is calculated at global scale and does not account for speci�c local aspects due to limited data access. EWR is the most uncertain variable of the method (Boulay et al. 2018).

6.2 Potential environmental impactAll information modules are reported separately. However, the total impact across all stages is also

presented.

Parameters describing environmental potential impacts were calculated using CML-IA method

version 3.04 (Guinee et al. 2001; Huijbregts et al. 2003; Wegener et al. 2008) as implemented in

SimaPro 8.4.0 Water scarcity potential was calculated using AWARE method (Boulay et al. 2018).


Environmental indicators describing waste generation were obtained from LCI except for

background information which has been calculated using EDIP 2003 method (Hauschild and

Potting, 2005). Table 12 shows waste and other outputs generated during each information
